Choral Singing Dataset

Choral Singing Dataset

This dataset was presented at the 15th ICMPC/10th ESCOM conference together with the paper: 

Cuesta, H., Gómez, E., Martorell, A., Loáiciga, F. (2018). Analysis of Intonation in Unison Choir Singing. In Proceedings of the 15th International Conference on Music Perception and Cognition.

It contains the individual audio recordings of 16 singers of the Anton Bruckner Choir from Barcelona (Spain) performing 3 different pieces a cappella, together with their associated MIDI files.

Singers were recorded in groups of four (4 singers per choir section), with individual close microphones with cardioid polar pattern for directivity purposes. The performance was virtually conducted by the conductor of the choir through a video, which was displayed in all the recording sessions for synchronization purposes. Singers also had the possibility to hear a piano reference (through headphones) for tuning purposes.

Three pieces were selected based on the choir repertoire and on the specific needs of the study, which were basically related to the language of the lyrics. These are the pieces we chose:

Locus Iste, written by Anton Bruckner (Latin).

Niño Dios, written by Francisco Guerrero (Spanish).

El Rossinyol, popular Catalan song.

Overall, this dataset contains, for each of these pieces, the tracks of each individual singer (16 singers), together with frame-wise f0 annotations, and note annotations and semi-synchronized MIDI files for each choir section.

Having the individual tracks also allows researchers to create the unison mix for each section, as well as the whole choir performance.

The dataset covers the frequency range between 87 Hz and 783 Hz and is especially dense between 150 and 450 Hz. The notes have durations that range between 0.15 and 6.21 seconds, with an average of 0.84 seconds.

The dataset is compressed into a zip file. In the decompressed folder there is a README file with all the information regarding the annotation files and the filenames.

合唱演唱数据集（Choral Singing Dataset）

本数据集于第15届国际音乐感知与认知会议（ICMPC）/第10届欧洲音乐认知科学学会（ESCOM）联合会议上，随研究论文一同发布，相关论文信息如下：
Cuesta, H., Gómez, E., Martorell, A., Loáiciga, F. (2018). 《齐唱合唱中的音准分析（Analysis of Intonation in Unison Choir Singing）》，载于《第15届国际音乐感知与认知会议论文集》。

本数据集包含来自西班牙巴塞罗那安东·布鲁克纳合唱团（Anton Bruckner Choir）的16名歌手的单人音频录音，他们演唱了3首无伴奏合唱（a cappella）作品，同时附带对应的MIDI文件。

录制环节以四人一组（每个声部配置4名歌手）开展，采用心形指向性近距麦克风以保障收音指向性。本次演唱由合唱团指挥通过视频远程引导，所有录制场次均播放该视频以实现演唱同步。此外，歌手可通过耳机聆听钢琴参考音以校准音高。

研究团队根据合唱团常备曲目与本研究的特定需求（核心关联歌词语言类型）挑选了三首作品，具体如下：
1. 《Locus Iste》，安东·布鲁克纳作曲，拉丁语歌词；
2. 《Niño Dios》，弗朗西斯科·格雷罗作曲，西班牙语歌词；
3. 《El Rossinyol》，加泰罗尼亚民谣。

总体而言，针对每首作品，本数据集包含16名歌手各自的人声轨道，同时附带逐帧基频（f0）标注、各声部的音符标注以及半同步MIDI文件。

凭借单人轨道资源，研究人员可自行合成各声部的齐唱混音效果，乃至完整合唱团的演唱混音作品。

本数据集的频率覆盖范围为87Hz至783Hz，在150Hz至450Hz区间尤为密集。音符时长介于0.15秒至6.21秒之间，平均时长为0.84秒。

本数据集以ZIP压缩包形式存储，解压后的文件夹中包含README文件，其中详细说明了标注文件与文件名的相关规范。
